Building envelope retrofitting

The deep renovation of the existing stock of residential and non-residential buildings facilitates the efficient use of resources, the reduction of waste and the mitigation of CO2 emissions. There are different solutions available to gain benefits in terms of energy and resource efficiency such as the use of premanufactured front-mounted façades to keep the existing building structures that are of cultural, architectural, historical and educational value.

Successful approaches include the integration of HVAC and photovoltaic components in the façades, semitransparent insulation, new glazing technologies and other innovations in construction components that provide architectural flexibility and decrease energy consumption. Energy supply units can be upgraded or replaced by state-of-the-art technology and room layouts reassessed and optimized. Ecological and energy-oriented refurbishment strengthens energy independence, reduces fossil fuel consumption, increases social well-being and shapes cultural identity of all European citizens.

SmartEnCity Site Tartu

Tartu has around 100,000 citizens and it is a compact university city. It provides a very good development environment, to a great extent due to its proactive city government. Demanding cross-sectorial cooperation is well established in Tartu, and it has internationally competitive R&D...

SmartEnCity Site Vitoria-Gasteiz

The implementation area of the SmartEnCity project in Vitoria-Gasteiz (Spain) is the Coronación neighborhood, which is a highly vulnerable area from a social and energy-efficiency point of view. With focus on neighborhood regeneration, the actions in the demo site cover three main areas: energy...

IMPRESS Site Coventry

Broadgate House is based in the city of Coventry in the United Kingdom. It is an office building owned by Coventry City Council. The building was constructed in 1953 and has a concrete frame with a brick front façade and curtain walling to the rear. The structure covers five storeys and includes a...

IMPRESS Site Drobeta Turnu Severin

Decebal High School consists of two main buildings, the old one was constructed in 1897 and is classic design, and the new one was constructed in 1970 and is a modern building, in comparison. The new part of the building will be renovated. The new school has five storeys above ground and one below...
